H-2 was sorbed in LaNi5 alloy and on multiwalled C nano tubes (MWCNT) at 313 K and 0-2 MPa to study the kinetics of sorption. The surface area of MWCNT was about 110 m(2)/g and the surface area of the alloy LaNi5 approached zero. The H-2 sorption capacity of LaNi5 was 2 orders higher than those of MWCNT. The time necessary for the sorption balance and the sorption kinetic curves differed considerably in both cases. The kinetics curve of LaNi5 was almost exponential but the first part of the MWCNT kinetics occurred almost immediate and made up 60% of the total change of the sorption capacity.
